Multi Language Integrated Electromagnetic Flow Meter for Sewage or Dirty Water

1. Introduction

MLF electromagnetic Flowmeter works according to Faraday's law of electromagnetic induction and is composed of sensors and converters. Used to measure the electrical conductivity of liquids or solids. In general, its electrical conductivity should be greater than 5 μ S / cm (the electrical conductivity of tap water and raw water is about 100 ~ 500 μS / cm), can also be used to measure various media such as acid, alkali, salt water, pulp or pulp. But these media cannot contain large amounts of magnetic materials and bubbles.

MLF electromagnetic Flowmeter is an instrument for measuring liquid fluidity. It is widely used in flow measurement in metallurgy, chemical industry, paper making, environmental protection, petroleum, textile, food, urban management, waterworks and other industries.

2. Quick Details

MLF electromagnetic Flowmeter is explosion-proof design.

function of low conductivity measurement.

There are 9 language options to meet the needs of different customers.

Have self-regulation function and self-examination.

different outputs are optional: hart, RS485 Profibus ,4-20 mA, frequency, pulse.

3. Selection of Liner Material

Liner Material Main Performance Application
PTFE

1 It has the most stable chemical properties in plastics, resistant to boiling hydrogen chloride and sulfuric acid, nitric acid, aqua regia, strong alkali and various organic solvents, but not resistant to chlorine trifluoride, high temperature nitrogen trifluoride, liquid fluorine, and liquid oxygen And ozone corrosion.

2 Low wear resistance.

3 Low negative pressure resistance.

1. -25~140℃

2. Strong corrosion medium, like strong acid and alkali

3. Healthcare medium

CR Oil proof, solvent resistance, oxidatite resistance and the resistance to the erosion of common medium like acid, alkali, salt, etc.

1. <80℃

2. Be able to measure sewage and mud

PU

1. Very good abrasive resistance, flexibility.

2. Low acid and alkali resistance.

1. <65℃

2. Neutral strong abrasion resistance medium

Hard Rubber

1 Room temperature, hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide

2 Avoid strong oxidizing agents

1. <80℃

2. General acid, alkali, salt solution

PFA

1. Can be used for most corrosive medium like acides, alkalis, and strong oxidant.

2. High material strength, resistance to aging, better than PTFE, EFP in high temperature

3. Injection molding for higher negative pressure

1. 40~180℃

2. Strong corrosion medium, like strong acid and alkali

3. Healthcare mdium

FEP(F46)

1. Hydrophobicity and non-viscous

2. Corrosion resistance is inferior to PFA

3. Negative pressure

1. 40~180℃

2. Strong corrosion medium, like strong acid and alkali

3. Healthcare mdium

4. Selection of Electrode Materials

Electrode Material Main Performance
316L

Good corrosion resistance of nitric acid, at room temperature <5% sulfuric acid, acetic acid, alkaline liquid, a certain pressure of sulphate, seawater, acetic acid and other corrosion, can be widely used in petrochemical urea, veline and so on.

Hb

Good resistance to all concentrations of hydrochloric acid below boiling point, as well as non-oxidizing acid, alkali, sulfuric acid, phosphoric acid, hydrofluoric acid and organic acid.

Hc

Corrosion resistance of oxidizing acids, such as nitric acid and mixed acid. A mixture of chromic acid and sulfuric acid, oxides, such as Fe3+,Q3+, and other oxidants, such as a mixture of hypochlorite solution above normal temperature and seawater.

Ti

Resistant to corrosion of seawater, various chlorides, hyalphates, oxidizing acids (including smoke nitric acid), organic acids or alkalis, but not pure reduced acids (e.g. sulphuric acid, hydrochloric acid). However, if the acid contains oxidants (e.g. nitric acid, Fe3, Q3), corrosion resistance is reduced.

Ta Good corrosion resistance similar to glass. Resistance to the corrosion of chemical medium(including hydrochloric acid and fumiing sulfuric acid), but can not be used for sodium hydromide fluid.
Pt-Ir Have good corrosion resistance of all acid, and can be resistance to the corrosion of alkali, all salt except aqua regia, ammonium slat and few other medium
Tungsten Carbide For pulp and sewage, good resistance to solid particle interference.
